The overall goals are to examine the effects of the ASMT compared to PRE on problematic anger, both self-reported and reported by significant others (SOs), both 1 week and 2 months after treatment; to assess the time course of treatment response during the treatment phase; to examine effects of the ASMT compared to PRE on a range of outcomes; and to assess the associations between case mix variables, including participant characteristics and injury variables, with treatment response.
